Seems like there was an issue with the link to register, but it should be fixed now. Use this link to be sure: www.mantini.co/mbk1

[@peterchristlieb]

Very nice, looks fantastic all put together. Getting the slop out of the chain shouldn’t be too big a deal. Run a torque converter or jackshaft and problem solved. If not, a spring loaded tensioner might do it.

[@mantinimotors]

Yeah 100% we have designed a jack shaft for it, but it hasn’t been made yet. But we were too excited to wait.

[@peterchristlieb]

@@mantinimotors Congratulations on doing what you want to do, prayers that it works out for you. I hope to be able to buy one of these in the not so distant future

[@danielspinler5351]

How much will it cost when done

[@brandonarmstrong3884]

Very cool build. Looking forward to more updates. My only concern is the ground clearance. With the pegs on doesn't seem like it leaves much room to lean while cornering?

[@mantinimotors]

That is a valid concern. The MBK-1 is designed more as a cruiser but it still takes quite a bit of leaning to hit the foot peg. Perhaps we should do a video to see how much it actually takes.

[@jessestacy7936]

Flip the clutch around to where the teeth are against the side cover, it keeps the chain from coming fully off the bike if it comes loose, it also protects for feet for when it snaps and starts smacking around a stuff.

[@mantinimotors]

Great advice. We would also typically have a chain guard, but we knew this was just going to be a short test ride and didn’t have one on hand to install.

[@Dowden_Official]

So exciting!

[@mantinimotors]

it really is!!!

[@Mememan867]

I would add if your chain isn’t already above a 35 chain I would upgrade it to a 40 chain or a 428 chain

[@mantinimotors]

We are going to run a 40 from the clutch to the jack shaft then a 35 to the rear sprocket. For now anyways since we want to test a few different variations to see what we like best.

[@escortmad]

It looks as if your chain is coming loose with the travel of the back shock when you install the chain it is under tension because the rear swing arm has full pressure on it and then when you ride it with weight on it and go over any small pump it looses tension and jumps off the sprocket.

[@mantinimotors]

100%. We should have waited for the jack shaft to be made before taking it for a test ride, but we couldn’t wait.

[@Mini.Moto.Guy806]

Great work guys‼️ it’s coming out great🫶

[@mantinimotors]

Thank you. It’s almost ready! Even though it was a short ride it was still sweet to finally be able to get it on the road.

[@mr.braapalicious]

Love the bike. I'm just a fat tire trail rider. But this looks great, even if it's a street cruiser. 😊

[@mantinimotors]

You can put fat tires on this if you want 👍 also, during the VIP presale, we will be showing a way you can make this off road ready.

[@diamondthomas7778]

All you need is a chain tensioner in a chain will stay on nice 👀 mini bike my guy 💯💯💯

[@mantinimotors]

For sure! We were just too excited to wait for the jack shaft being made.

[@brandonwebb2529]

It happens all the time to me on my coleman if the chain doesnt have tension the teeth on the sprocket or clutch will break it fron the chain jumpin off ...slow n steady wins the race

[@myst113]

this is awesome man congrats 🎉 you definitly need to get some tention on that chain but that build is awesome man!

[@mantinimotors]

Oh yeah, the jack shaft will help with that 100% and we may even add a chain tensioner to the swing arm itself to make it even more secure.

[@marklaramie7393]

That will be the coolest/best bike on the market 👍

[@mantinimotors]

Thank you! We really wanted to design something different. Glad you like it!

[@bradygainey8043]

Looks great can’t wait to buy one

[@mantinimotors]

Can’t wait to see what you do with it!

[@Frokul]

looks like a dream come true cant wait

[@mantinimotors]

It really feels like it is!

[@jimmybrown788]

Need a chain tensioner to keep the chain from bouncing so much

[@mantinimotors]

For sure, we just were to excited to wait for the jack shaft to be made before taking it for a test ride.

[@laurelfisher2689]

Making progress, and I want to see the finished product. Before getting to the pre-purchase list.

[@mantinimotors]

For sure, that makes sense. During the ViP presale we will be unveiling the final look. The one in the video is just the first one to test proof of concept. Now that we know everything does work, we can make the necessary modifications to the design to make it perfect. 👍

[@josepholivas7682]

Certain clutches are able to be flipped. Have the teeth on the inside today’s the engine but going to need a spacer so you won’t be too close to the motor. So you won’t need a tensioner. Hope this helps fam 💪🏽

[@mantinimotors]

Thank you. Yeah, the clutch we have does do that, which we could have tried. But we are just waiting on the jack shaft to do a proper test ride. Coming soon!

[@Adam_3]

As a day one supporter I've been waiting for this video🔥🔥

[@z1berzerker]

Totally 👍😎😊... take my money 💰 🤪

[@mantinimotors]

That’s amazing! And we appreciate the support. Only 12 days to go!

[@fredericklogue6566]

Was thinking of using your frame for the Go power sports 180. Do you believe it will hold up for a off road race like that? I can beef it up, will need to be able to handle 22 HP or so... Think she will do it? That would get your name out there big time at no cost to you.

[@mantinimotors]

I do believe the frame is more than capable of handling the GPS 180 as it is built from 1 inch tubing. I do agree that you might need to upgrade the suspension to give you more travel as this frame is more of a street style bike. We are going to develop an off road kit for this bike, but I’m not sure if it will be ready by this November. But it would be epic to see you race it in the event.

[@sekovittol3124]

Where did you get a power-fist'r that is not blue in colour? I am currently putting in an electric start power-fist 212. Did you know that power fist motors don't have a piston and con-rod, they have a forearm and a fist inside instead.

[@mantinimotors]

Haha, we got it from Princess Auto. I think all the new ones are now black.

[@sekovittol3124]

@@mantinimotors Mine has been sitting in a box for almost a year, got it out, put in oil and gas, it started first pull. Going to get a battery soon and I will hook up an LED light to the battery.

[@kipbreitmeyer8517]

I'm not sure that you have purposely designed the swing arm to accept bigger tires, but that looks pretty awesome.

[@mantinimotors]

Right now we have a 10” rear wheel which fits perfectly. But if you decided to go rigid, you have more than enough room for a larger rear tire if you want to go that route. One day we may design a larger swing arm if there is a demand for it.

[@miguelpagansr6128]

If the price for whole kit is reasonable minus the engine, I would sell my minibike and vintage scooter to buy one.😅 Looks like you'll need an automatic chain tensioner.

[@mantinimotors]

Well you’re in luck, our VIP presale is happening right now and ends tomorrow at midnight. So if you head over to our website you can see all the options we have and watch the full presentation that goes over all the features and so much more. www.mantini.co

[@CheapMechanics101]

We need another update on the build

[@mantinimotors]

The update is this Saturday at 1pm EST during our VIP presale 👍 will you be joining us?

[@kipbreitmeyer8517]

Are you going to sell just the frame? Very interested in one.

[@mantinimotors]

Yes we will be selling a frame kit and we have partnered with Go Power Sports to offer an exclusive parts kit to turn the MBK-1 into a full roller.

[@brandonwebb2529]

Amazon has chain tensioners for this

[@mantinimotors]

We have designed a jack shaft but it wasn’t ready yet, so we took a chance with the long chain. Once we get the jack shaft, we can do a proper test.

[@brandonwebb2529]

Definitely a 5 grand bike

[@mantinimotors]

Appreciate you saying that. A lot has gone into building it but I think you’ll be happily surprised when we reveal the price during the presale on the 27!

[@outcome2715]

Chains to long , slow the video down right before it pops off you’ll see a surge shooting towards the centrifugal clutch sprocket ( like if you were to take a rope and in a quick motion jerk in up and slam it down , the little wave that happens is what I called a surge it happened to your chain) also know because I just went through the same problem 😂 , put a tensioner on for now till I can buy a welder to swap out my 105cc in my razor dirt bike to a 212cc lol 🎉 105cc I hit around 25-32 mph not bad for what it is , but I wanna be able to ride wheelies so 212 should be what I need for the torque the 105cc can barely stand the bike up you gotta low rev for about 1-2 seconds to get tension on the chain then gun it and it’ll come up but it’s impossible to keep it there just not enough torque edit - sorry for the book but another thing I noticed was your centrifugal sprocket is on the outside of the clutch ? Mine is on the inside (between clutch and engine lol ) I’ve never seen them on the outside but doubt that’s why it’s popping tbh

[@mantinimotors]

100%. This was just a test but we should have waited for the jack shaft to be made. This way we wouldn’t have had to run such a long chain like this.

[@thedude7726]

Id like to see this with a cvt. They .ake such a huge difference it's unbelievable

[@mantinimotors]

For sure, we will be getting one for the 670cx we have and will be putting in 100%.

[@RetroYamaha]

Looking good

[@mantinimotors]

Thank you!

[@northminibikes]

It ain't easy!!

[@mantinimotors]

Not when you’re trying to build something new. But it’s fun, that’s for sure.

[@boa2143658709]

I love the frames look but man if any deserve a springer front end its this.

[@mantinimotors]

Now that’s an idea!

[@boa2143658709]

@@mantinimotors a scaled down version of motorcycle springers would look amazing with the frames curves youve designed.

[@mantinimotors]

@@boa2143658709 perhaps that will be an option we offer in the future. We will have front suspension though, this rigid front end was just to test the bike.

[@kene6838]

You’re going to have issues with that taper bearing and premature wear without a dust seal.

[@mantinimotors]

Thanks for the tip. I’ll discuss that with Tom and see what he thinks.

[@GENERALCHAOS13]

That looks like my 1978 Honda G400 would Fit in nicely

[@mantinimotors]

If it is less than 19 inches tall, shouldn’t be an issue.

[@GENERALCHAOS13]

I posted the video of the Engine on my channel

[@user-yi3xu9fr5m]

after i clicked register it said page not found

[@mantinimotors]

Oh weird. Did the one in the description work?

[@zaydenpayne9303]

Really hoping I can score 1 of the first 25!

[@mantinimotors]

Just make sure to show up to the live stream early to ensure you get in 👍

[@danielllavore7507]

Are you concerned about the angle of that shock

[@mantinimotors]

Not at all, it actually worked really well. We will do an entire video on the rear shock once we get the next frame back from the shop and we will test it at every angle and stiffness. We will also try a softer shock as the current one on the bike is rated for 2,000 lbs which may be too tough. But there is room for adjustment on the shock itself as well.

[@shawnmann1781]

It needs a single backbone design so you can put a fuel tank on it

[@mantinimotors]

We are actually going to design a tank to work with the double backbone 👊

[@Clappedout_films]

Chain broke because your clutch needs to be flipped. Sprocket side in

[@mantinimotors]

Yeah, we could have done that for sure. Next time will give it a try, but the jack shaft will help a lot.

[@Clappedout_films]

@mantinimotors I’m excited for the build man I want one !!!

[@protobeat5384]

put a 1000cc in it
